Application iilcd March 11, 1885.

T0 all whom, t may concern:

Beit known that we, JOSEPH M. HOYT and WILLIAM G. Herr, both of Lynn, in Ythe county of' Essex and State of Massachusetts, have invented, jointly, new and useful Improvements in Bottle-Vashers, of which the following, taken in connection with the accompanying drawings, is a specification.

Our invention relates to machines for washing bottles, and is an improvement upon the inventions described in Letters Patent No. 213,583, granted to O. A. Miles and E. R. Lovett, March 25, 1879, and No. 238,289, granted to Joseph M. Hoyt, March l, 1881, and is designed to remove or obviate certain difficulties which have attended the use of machines constructed according to the descriptions in those patents. In those machines a cylindrical receptacle or sleeve is provided for the brush when it is not within the bottle. This receptacle is formed of two concentric shells or tubes provided with bellshaped mouths to receive the mouth of a bottle. The rotary shaft which carries the brush enters the receptacle at the end opposite the bellmouth. rlhe receptacle is made to slide along this shaft to allow the brush to enter the bottle. The outer sleeve or casing is so connected with other parts of the machine that it has only the sliding movement. The inner sleeve is supported by the outer casing, and not only slides along with it upon the shaft, but revolves with the brush when it is drawn over and surrounds the brush. The frequent sliding of the sleeve along the shaft, which is rotating at a high speed, causes great wear of the shaft, and of the bearing in the sleeve through which it passes. XVe have found by experience that considerable water is carried into the receptacle with the brush when said brush is withdrawn from the bottle, and escapes from it both from the bell-mouth and from the opposite end around the shaft. rllhat which escapes from the mouth is by the rapid rotation of the receptacle thrown off from it laterally with considerable force, causing much inconvenience and discomfort to the operator. That which escapes from the opposite end is in like manner thrown off, and with the like inconvenience, by the rapid rotation of the Serial No. 158,428. (No model.)

shaft. Ve have also found another difficulty with the inner sleeve constructed as described in said patent to Hoyt. Vhen the neel; of the bottle was placed in the mouth of the sleeve and pressed against it with sufficient force to move the sleeve backward, the friction of the bottle was often sufficient to prevent the-inner sleeve from revolving, so that during the movement back and forth of the sleeve the brush was subjected to more or less destructive wear. The action of the bottle in preventing the rotation of the inner sleeve and the action of the corneal mouth in throwing off the water laterally are prevented by forming the mouth wholly upon the outer casing, as will be hereinafter fully described, and the escape of the water around the rotating shaft by the introduction of a stuffing-box and packing around the shaft Within the sliding brush-receptacle.

Some other improvements relate to details of construction designed to give facility in the adjustments of parts of the machine to prevent undue wear and insure its highest efciency, all of which will readily be understood by reference to the description of the drawings, and to the claims to be hereinafter given.

Of the drawings, Figui-el represents a plan of a machine embodying our invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a vertical section of the stand E, showing the driving and loose pulleys, the bearings for their shaft, and the shipping device in elevation. Fig. represents a longitudinal vertical section through one of the bearings of the sleeve-carrying cross-head, showing in elevation one of the cords and its pulley for moving said cross-head and sleeve toward the front end of the machine. Fig. 5 represents a central longitudinal section of the brushinclosing sleeves,with the brush and a portion of its tubular spindle in elevation. Figs. 6,

7 ,and 8 represent details to be hereinafter referred to.

In the drawings, A is a hollow column having a lateral pear-shaped opening cut through from side to side thereof, and provided with the bearings A A', in which is mounted the shaft B, upon the rear end of which is mount- IOC l 2 e v329,390

ed the driving-pulley B,and upon its middle, .within the column A, the pulley C.

D is a drip-pan, secured near its rear end to the upper end of the column A, and further supported, toward its front end, by the brace D, the office of said pan being to catch the drippings of water which flows to the rear therein, and is discharged through au opening in said pan at a, fromwhich'a pipe (not shown) may convey it to any desired point.

E is a stand, also secured to the upper end of the column A, and provided with the bosses E E', which receive and support the rear ends of the parallel guide-rods F F, the front ends of which are supported in corresponding bosses on the stand G,secured to and supported by the drip-pan D, as shown in Fig. 2. The stand E has formed therein the two sockets b b, to receive the cylindrical stems of the forked supports H H, provided with screwcenters o c, upon which are mounted the boxes I I in a well-known manner. The forked supportsHH and the boxes I I, supported thereby, may be adjusted vertically by means of the set-screws d d, which act upon the lower ends of their spindles, and may be secured, when properly adj usted,by the set-screws e e. The boxes I I have mounted therein the short tubular shaft J, firmly secured to the smaller. tubular shaft or pipe J ,whieh extends through said shaft J at both ends, as shown in Figs. 1, 2, and 3.

K is a pulley firmly secured upon the shaft J, so as to revolve therewith; and K is a corresponding pulley mounted loosely upon said shaft, or so as to revolve freely thereon.

L is the belt by which motion is transmitted from the driving-shaftB toy the shaftJ and tubular brush-carrying spindle J', and said belt may be shipped from the tight to the loose pulley, or vice versa, by means of the shipper-bar M, mounted in bearings f f, formed upon and projecting'upward from t-he caps of the boxes I I, and the curved ngers g g, mounted thereon, as shown in Figs. l, 2, and 3. The tubular spindle J carries at its front end the brush-holder N, constructed substantially as shown and described in the beforecited Letters Patent to J. M. Hoyt, and is connected at its rear end to the fixed valvecasing O in the same manner as described in said patent. To the rear end of the valvecasing O is connected the water-supply pipe h, as shown in Fig. 2.

P is a cross-head mounted upon the parallel guide-rods F F, so as to be moved to and fro thereon, and is provided -at each end with an ear or lug, z', to which is connected one end of a cord, i', which, after passing overa pulley or sheave, j, has its other end connected to one end of the Weight Q, by means of which said cross-head is held in its normal position at the front end of said guide-rods until sufficient pressure is applied to it to raise said till it strikes the adjustable stop-collar W. (Shown in Figs. l and 2.) The cross-head P is provided in the center ofits length with a bearing to receive the sleeve R, and is bi furcated for some little distance upon each side of said bearing, to enablethe two parts of said bearing to be sprung together to clamp said sleeve and hold it firmly in position therein by the clamping-bolts 7c k, as shown in Figs. 1 and 8, the object of which is to enable the sleeve R to be adjusted so that its front end shall be at a a greater or less distance from the front end ofthe brush-carrying spindle J thereby adapting the machine to washing different kinds of bottles requiring different lengths of brushes. The sleeve R is provided at its rear end with a stuffing-box or packed bearing, l, to fit the' spindle J and make a water-tight connection therewith that may be moved endwise thereon and allow the spindle to revolve freely while the sleeve is held stationary in its bearing in the cross-head P. The sleeve R is bored out to a larger interior diameter at its front end than at its rear end to receive the secondary sleeve S (see Fig. 7) and the collar R', the latter being secured to the sleeve R by the screw m, the interior of the collar It and the front end of the sleeve R being made flaring or bellmouthed, as showninFigs. 5 and 6, to receive Vthe end of the bottle-neck, while the sleeve S fits loosely in the chamber thus formed in the sleeve R, and remains stationary with said sleeve R when the brush is within the bottle, but revolves freely with the brush when the brush is drawn within the sleeve, as shown in Fig. 5.

T is a rod mounted so as to slide freely endwise in bearings in the ears P on the crosshead P and E2 on the stand E, and connected at its rear end with the lever U, secured to the screw valve-stem n, as shown in Figs. 1 and 2 as a means of opening and closing thevalve in the casing O for letting on or shutting offthewater. A coiled spring, V, surrounds said rod T forward of the bearing E2, to which one end of it is secured, while its other end is passed through a hole in said rod at o, and secured thereto in such a manner that when the rod T is moved forward into the position shown in the drawings and the valve is closed the tension of said spring shall tend to move said rod toward the rear and open the valve. The rod T has secured to or formed upon its front end the'head p, having set in the side thereof the pin p', with which the pivoted hook g may be engaged, as shown in dotted lines, to prevent abackwardmovement of the rod T when the cross-head l? and sleeve R are moved back to remove, adjust, or clean the brush, thus preventing the opening of the valve, and the consequent letting on of the water at such times, which would not only be a waste of water, but interfere materially with the operator in the performance of his duties in that connection. On the front end of the rod T, between the head p and the ear P on the cross-head P, is

rio

placed the short spiral spring r, which serves as a yielding cushion to receive the blow of the cross-head that would otherwise be given to the head of the rod T when the pressure is removed from the sleeve R, so that the rod T may be slightly moved after the valve is closed, and thus insure a perfect closing of the valve without screwing it down so tight that the spring V cannot open it again when the crosshead is again moved to the rear. The crosshead P is provided at each end with a long hub or pipe bearing, P2, which embraces the guide-rod F, each of said bearings being provided with two anttfriction balls, tt, mounted in adjustable screwbearing sockets s s, one upon the upper side of the guide-rod, near the front end of the hub P2, and the other beneath the guide-rod and near the rear end of the hub P2, as shown in Fig. 4. The heavy forward end of the sleeve R has a tendency to cant the cross-head P and cause its bearings upon the guide-rods F F to bind and increase the friction to such an extent as to make the machine work hard, to obviate which we use the anti-friction balls t t, arranged to bear upon the upper and under side of the guide-rod, and made adjustable for taking up the wear, as shown and described. The weight Q must be of suflicient capacity to overcome the tension of the spring V, so as to move the rod T forward and close the valve to shut off the water from the tubular spindle J when the bottle is removed from contact with the sleeve R. When it is desired to change the brush, or for any reason to move the sleeve R off from the brush N without inserting the brush into a bottle, the hook-latch q is made to engage with the pin p', and the cross-head P and sleeve R may then be moved back to uncover the brush without opening the valve to let on the water, the hook q preventing the tension of the spring V moving the rod T to the rear. Another advantage of this arrangement is that when the crosshead has been moved back, as above described, the tension of the spring V, acting upon the rod T, tending to move it backward, and the resistance of said hook to such backward movement, together with the peculiar relation of the pivotal connection of said hook relative to said rod, causes a depression of the forward end of the rod T to such an extent as to cause suficient friction between said rod and its bearing in the ear P to retain the cross-head in said retracted position until moved forward by force.

The operation of the other parts of our invention will be readily understood from the foregoing without further explanation here.

Vhat we claim as new, and desire to secure by Letters Patent of the United States, is-

l. The blush-receptacle herein described, having a non-revolving but removable funnelshaped mouth-piece to receive the neck o f the bottle, and an inner revoluble sleeve havlnga uniform inner diameter throughout its length, which diameter is the same as the inner diameter of the rear portion of the outer xed sleeve and the smallest diameter of the funnelshaped mouth-piece, all arranged and adapted to operate substantially as and for the purposes described.

2. The combination of the guide-rods F F, the cross-head P, two anti-friction balls, tt, and two adjustable sockets, s s, set in each end of said cross-head, substantially as described.

3. The combination of the guide-rods F F, the cross-head P, and two anti-friction balls, t t, and adjustable sockets s s, set in each end of said cross-head, one near one end of the bearing of said cross-head and below the rod F, and the other near the other end of said bearing and above said rod F, substantially as described.

4. The combination, in a bottle-washer, of the revolving tubular brush-carrying spindle J', the boxes I I, the forked supports H H, the screw-centers c c, the stand E, and the set-screws d d and e e, all arranged and adapted to operate substantially as described.

5. The combination, in a bottle-washer, of the movable cross-head P, the headed rod T, mounted in guide-bearings and passing freely through the ear P of said cross-head, so as to permit a free movement of said cross-head without moving said rod, the spring V, constructed and applied to move the rod T toward the rear of the machine to open the valve, the valve O n, and the lever U, forming a positive connection between the valve and the rear end of said rod T, substantially as described.

6. The combination, in a bottle-washer, of the valve O n, the lever U, the rod T, provided with the head p, the springs V and r, the crosshead P, the cords t i', the pulleys j j, and the weight Q, all arranged and adapted to operate substantially as described.

7. The combination of the crosshead P, provided with the ear P', the valve O n, the lever U, the rod T, provided with the pin p, the spring V, and the catch q, all constructed, arranged, and adapted to operate substantially as and for the purposes described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 9th day of March, A. D. 1885.
